Storage system
A storage system comprising a drawer frame and one or more boxes. The drawer frame comprises first and second guides with a U-shaped cross section, which is open towards the interior of the drawer frame such that flanges of a box can be inserted into the guides to thereby support the box slideably in the drawer frame. Clips are attached slideably to the guides and engage with the box through a clip connection device interacting with a box connection device of the box, which prevents the box from falling out of the frame.

The following co-pending and co-assigned application contain related information:
U.S. Nonprovisional patent application Ser. No. 15/309,100 for A Lid and a Storage System, filed concurrently herewith; and
U.S. Nonprovisional patent application Ser. No. 15/309,111 for Container and Storage System, filed concurrently herewith.
TECHNICAL FIELDThe present invention relates in general to storage systems, and in particular to modular storage systems including drawer frames and containers.
BACKGROUNDStorage systems are widely used for storing items such as linen and laundry, typically with a container in the form of a metal wire or mesh basket, or the like. One problem with such systems is how to make them more versatile and easy to handle for an end user.
SUMMARY OF INVENTIONOne object of the present disclosure is therefore how to provide a system of the initially mentioned kind that is more versatile and easy to use.
This object is achieved by means of a system including a container and at least one clip. The clip is adapted to be slideably attached to a drawer frame guide, with a C-shaped portion of the clip embracing said guide, and to engage with the container with a clip connection device interacting with a container connection device of a flange of the container, such that the clip becomes fixed with regard to the container in the longitudinal direction of the guide. The clip prevents the container from being fully pulled out of the drawer frame and thus prevents the container from falling out of the frame. This makes the use of the system easier for an end user. Further, the clip assists with preventing the deformation of the container if the container is provided with a heavy load, by keeping the flange in connection with the guide of the drawer frame.
The container connection device may be an opening in a container flange, and the clip connection device may be a connector tab of the clip, which tab is adapted to enter the opening, and the end of the connector tab may comprise a tip that is directed inwards, towards the frame guide when the clip is attached to the flange.
The clip may be adapted to abut a drawer frame bar at a stop position of the box, thereby preventing the box from exiting the drawer frame.
The container may be a box that is made of injection molded plastic such as typically polypropylene, and the clip may be made of injection molded plastic such as polycarbonate.
The present disclosure is related to modular storage systems including drawer frames and containers. Such systems have the benefit, e.g. as compared with a traditional chests of drawers, of being configurable in various ways to address the needs of an end user. Drawer frames with metal wire and mesh baskets have been widely appreciated by users that have been able to select wire and mesh baskets with different sizes according to their needs.
From a producer point of view, the components involved have allowed for efficient distribution as empty containers can be nested inside other empty containers and since drawer frames can easily be assembled by the end user. This of course reduces the cost of the final system.
It is suggested to include plastic containers with lids in storage systems of this kind as a complement to wire and mesh containers. This would make storage systems of this kind even more versatile.
Plastic containers are relatively inexpensive to produce in large series by injection molding. Unlike a mesh or wire container, a plastic container may be made diffusion tight, and when lids are attached to the containers, the they become stackable, such that a number of containers, with items stored inside, can be stored on a small floor surface. If the storage system is used for instance in a closet, this allows the user e.g. to switch the contents of the closet from season to season.
For instance, during off-season, winter clothes may be stored at another location and, thanks to the more or less diffusion tight properties of the containers, are protected from moisture, etc. When the clothes are needed again, these containers may replace others in the drawer frame. Such a procedure is much more efficient than moving clothes from a drawer to another box, back and forth. The present disclosure provides solutions that make a plastic container more suitable for a storage system of this kind, thereby contributing to accomplishing the goal of obtaining a more efficient and versatile storage system.
The present disclosure relates to a container that is used in connection with a drawer frame. An open plastic container 1 in the form of a box is shown in
The box has flanges at the upper edges of at least one pair of walls. The flanges extend outwards from the interior of the box in a direction substantially parallel or close to parallel with the plane in which the bottom portion 3 extends. This allows the box to be inserted in a drawer frame.
Such a drawer frame 15 is shown in
The present disclosure seeks to improve container/drawer frame combinations of this kind. This is done by applying a clips on each side of the box that is connected both to the guide and the box.
As is more clearly shown in
The clip 23 includes in cross section a C-shaped portion 25 which in
The end of the connector tab 27 may include a tip 29 that is directed inwardly, towards the opening of the C-shaped portion. Further, the inner of the C-shaped portion may include one or more recesses 31 that facilitate mounting of the box in the drawer frame as will now be described. The recesses are more clearly shown in the reverse perspective of
The clip 23 is then turned outwards until it reaches the position in
In this position, the clip snaps into engagement with the box flange 19, and with the C-shaped portion embracing guide, if the box is pulled outwards, the clip will follow, sliding on the guide 17. However, as is evident from
Additionally, the clip adds some structural strength to the box 1. For instance, in the situation is illustrated in
The present disclosure is not limited to the example described above and may be varied and altered in different ways within the scope of the appended claims. For instance, the opening in the container flange, in which the tab of the clip enters need not be a through hole, a recess may be sufficient. Further, the clip may abut against another item than a frame bar to prevent the container from exiting, such as for instance a stop screw or clamp that may be attached to the guide at a chosen location. In principle only one clip per container is needed to provide the stopping function.
